i'm separating a script that has worked into separate slave and master modules as described in http://salilab.org/modeller/manual/node435.html.

my master script looks like this:

> j = job() > j.append(local_slave()) > j.append(local_slave()) > > for afile in alignFiles: > > alnRunDir = '%s%s/' % (dataDir,aname) > if not os.path.isdir(alnRunDir): > print "doAllAlign: Creating directory",alnRunDir > os.makedirs(alnRunDir) > > for runIdx in range(nruns): > j.queue_task(SeedTask(argumentList)) > > for result in j.yield_tasks_unordered(): > print result

and my slave task like this:

> class SeedTask(task): > """A task to read in a PDB file on the slave, and return the resolution""" > > def run(self,dataDir,afile,aname,runIdx,randMethod,knownLbl,seqLbl,nmodPerRun,atomDeviation ): > env = environ() > env.io.atom_files_directory = [dataDir] > arg4seed = - (int(runIdx) + 2) > env = environ(arg4seed) > > runDir = '%s/%s/run_%02d/' % (dataDir,aname,runIdx) > if not os.path.isdir(runDir): > print "doAllAlign: Creating directory",runDir > os.makedirs(runDir) > > os.chdir(runDir) > > a = automodel(env, alnfile=afile, > knowns=knownLbl, sequence=seqLbl, > assess_methods=(assess.DOPE, assess.GA341)) > > a.starting_model = 1 > # 2do: test task / run ratio? > a.ending_model = nmodPerRun > > a.deviation = atomDeviation > if randMethod=='XYZ': > a.rand_method = randomize.xyz > elif randMethod=='DIHEDRAL': > a.rand_method = randomize.dihedrals > > a.make()

i'm stepping thru with a debugger, and it gets to the yield_tasks_unordered() generator in the master. but as i attempt to make the next step it throws an exception that seems to have to do with env.io.atom_files_directory now (in the master/slave version) not getting set correctly?

would you know what i'm doing wrong here? thanks again for your help.
